如图1至图4所示，本发明揭示了一种电子电脑锁，其包括锁座1以及设于锁座1上的卡块组立2、缆绳头3、锁舌组立4、电机5和电路板6。卡块组立2包括两卡块21及一活动设于两卡块21之间的滑块22，两卡块21铰接于锁座1上；缆绳头3连接滑块22；锁舌组立4包括锁舌壳41和锁舌42，所述锁舌42一端可转动地连接于锁舌壳41，另一端与缆绳头3活动配合；所述锁舌壳41上设有一凸块411；电机5连接有一与凸块411活动配合的凸轮51；电路板6连接电机5。
锁座1作为外壳，其上连接有锁盖7。锁座1与锁盖7配合以将其他组件封装于内。电机5和凸轮51构成驱动机构。
卡块组立2还包括两相互连接的转动轴23，两所述卡块21分别铰接在两转动轴23内，两转动轴23固定在锁座1上。本实施例中卡块21与转动轴23铰接，然后再通过转动轴23固定在锁座1上。实际应用过程中，也可以将卡块21直接铰接于锁座1上。
卡块21朝向另一卡块21的侧面设有第一凸台211，所述第一凸台211位于卡块21连接电脑的一端。当滑块22退出两卡块21的第一凸台之间时，卡块21的两第一凸台211能够贴合在一起，从而使卡块21能够从电脑接口中脱离出来。
为了能够使滑块22能够顺畅地在两卡块21之间活动，卡块21的第一凸台211形成有一斜面213；相应地，所述滑块22远离缆绳头3的一端设有两斜导面221，该斜导面221与第一凸台211的斜面213配合。
为了避免滑块22在滑动时从两卡块21之间脱离，卡块21朝向另一卡块21的侧面设有一朝向另一卡块21凸起的第一限位台212；相应地，所述滑块22朝向卡块21的侧面上设有第二限位台222，所述第二限位台222靠近滑块22连接缆绳头3的一端。第一限位台212的上端面为倾斜状，第二限位台222可在该第一限位台212的上端面滑动。
缆绳头3与滑块22连接，以便拉动缆绳头3时能够带动滑块22运动。在本实施例中，缆绳头3上设有一卡槽33，滑块22上设有一第二凸台223，缆绳头3与滑块22通过第二凸台223和卡槽33进行卡接。
锁舌组立4还包括扭簧43、固定销44和弹簧45，所述扭簧43设于锁舌42内，所述固定销44穿设在锁舌壳41、锁舌42和扭簧43中。所述弹簧45一端连接锁座1，另一端连接锁舌壳41，为锁舌壳41及锁舌42提供回复力。本实施例中通过扭簧43和固定销44实现锁舌42与锁舌壳41的可转动连接。
缆绳头3上形成有两与锁舌配合的容置槽311、312，两容置槽311、312之间设有第三凸台32，所述锁舌42与该第三凸台32活动配合。两容置槽分别为第一容置槽311和第二容置槽312。
如图5至图11所示，本发明的工作原理如下：
输入一信号(蓝牙信号，指纹，按键等)，当信号匹配时，电路板6控制电机5转动90度，带动电机5凸轮51转动到缺口位置，此时，拉动缆绳头3，可推动卡块组立2的滑块22滑动，从而使缆绳头3可向外拉动一段距离，同时缆绳头3带动滑块22一起向拉动方向运动，滑块22运动的同时使两个卡块21向内闭合，从而实现开锁。
向外拉动缆绳头3时，滑块22随着缆绳头3向下滑动，使得滑块22从两第一凸台211之间脱离出来。滑块22继续滑动，其上的第二限位台222沿第一限位台212上端面滑动，使得两第一限位台212之间的间距增大。在杠杆作用下，两卡块21以铰接位置为支点，当两卡块21的第一限位台212逐渐张开，两卡块21另一端即两第一凸台211则逐渐靠拢，从而失去锁紧力。继续拉动缆绳头3，则可将卡块组立2拉出，即完成电脑锁的开锁操作。
开锁后锁舌42位于缆绳头33上的第一容置槽311内，锁舌组立4在后端弹簧45的作用下回到初始位置，间隔一定时间后，程序控制电机5回转，同时带动凸轮51回转，凸轮51缺口位置偏离，此时锁舌组立4的凸台被凸轮51挡住而滑动被限制。
当再次进行上锁时，推动缆绳头3，带动锁舌组立4的锁舌翻转，从而使缆绳头3可向内推动一段距离，同时缆绳头3带动滑块22一起向外运动，滑块22向外运动的同时式左右两个卡块21向外张开，从而实现上锁。
推动缆绳头3时可带动滑块22滑动，其斜导面221沿两滑块22的斜面向上滑动，并进入两第一凸台211之间，使得两第一凸台211张开与电脑端锁紧，从而完成电脑锁的上锁操作。
综上，本发明的关键在于，本发明的电子电脑锁由锁座、卡块组立、缆绳头3、锁舌组立和驱动机构组成，其中缆绳头3配合卡块组立即可实现对电脑的上锁操作，驱动机构、锁舌组立配合驱动机构即可实现对电脑的解锁操作，整体结构简单，体积小。而且，本发明驱动机构有电机配合凸轮实现，结构简单，也进一步减小了电子电脑锁的体积。
而且，本发明的卡块组立有两卡块21和置于两卡块21之间的滑块22构成，其通过缆绳头可以使滑块22活动配合于两卡块21之间，即可实现卡块组立锁电脑端的锁紧或解锁。其结构简单，结构稳定，能够实现电脑锁与电脑端的稳固连接。
以上所述，仅是本发明实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
